WALKERVILLE, ONTARIO, CANADA.

TRAILER.

Application filed January 18, 1917.

T 0 all whom it may concern:

Be it known that I Oaua E. BYRON a c1t1- zen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Trailers, and declare'the following to be a full, clear, and exact description of the same. such as will enable others skilled in-the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part the tongue may be allowed to swivel with respect to the draft bar, or on the other hand,

the tongue and draft bar may be locked to-. gether and the wheels allowed to swivel in accordance with the movements of the combined draft bar and tongue. It is to pro vide an improved meansto effect these results and a draft rigging and steering gear connected directly with the frame that the v present invention is designed.

Provision is made to accommodate the steering gear to the relative movement permitted between the frame and axle by the y the bottom of which are a pair of shoulders In the drawings: Figure 1 is a plan view. 7

comprises a coupling head d having a rearward extension which pivots by the bolt 6 to the draw bar f. The lower end of this bolt (2 enlarges and forms a ball-like head 9 that engages in the slotted and bored end it of the compound steering link (detail Fig. 6). The rear end of the front link i is provided with a hub adapted to engage in the throat otthe yoke 7a, a pin Z with suitable cotters pivoting the front link i to this yoke-like head of the rear link on. This compound draw link or i is connected with the steering arm n by means of the drag link 0. By reason of the hinging. connection between the front draw link and the rearidraw link m it is evident that the compound draw link may accommodate itself to the different relative positions of the frame and the axle due to tie spring suspension; especially is Patented Nov. 12,1918.

this so as the slotted and bored end it of the front draw link 2' has the loose connection with the bolt 5.

It will be noted that the rear link mis a.

casting which not only contains the yoke head but contains a sleevelike portion 12' 'couplinghead comprises a casting with the usual bell-like head .5' on the insideand on t t. The rear end of the draw bar of the I preceding vehicle is provided with a pro ecting cross pin it whose ends can be dropped behind the shoulders t, the dog o may then be turned up which prevents the ends of theflcross pin a from rising above the shoulders. It will be noted that the draw 'bar of the preceding vehicle is a twopart one in which the two parts have relative' longitudinal movement resisteddoy suitable buliersprings 0/) which need only here .be referred ,to generally.

The axle b and the fra me are connected by radius rods 00 whose .purpose is the usual one of serving. to commun'icatethe pull of the frame to the wheel of the car without utilizing 'the spring. The draw barf is provided with an upwardly projecting nub y socketing the spring retained and hook- ,like latch z. Recesses 2 are provided forward and. aft on thenub, each-adapted to pair with asimilar recess 3 on the frame and a similar recess 4 on the coupling" head. Obviously the latch max have its hook engaging in the pair of recesses 2, 1:3 (Fig. 2) ke ving the draft bar and frame together and allowing the coupling head to swivel, or the latch may have its hook engaging with the pair of recesses 2, keying the coupling head and draft bar together to allow them to swivel as a unit in the frame. .l'lcnce the wheels of the trailer may be allowed to swivel for steering purposes or may be locked in non-swiveling position.

What I claim is:

1. In a vehicle. the combination of an axle, a frame, a spring for supporting the frame upon the axle, a compound steering lever having two parts, one of which is pivoted to the axle swiveled together to allow for the. relative movement of the frame and axle, a draw and steering bar having a loose connection with the steering lever and mounted upon the frame.

In a vehicle, the combination of an axle, a frame, a spring for connecting the.

axle and the frame, draft. rigging comprising a draw bar piv' oted to the frame. wheels swi veled to the axle, a steering lever pivotally supported upon the axle and connected with the draw bar and with the steering wheels and arranged to allow for the relative movement of the axle and frame.

3. In a vehicle, the combination of a frame. an axle, a. spring for supporting the frame upoir the axle, steering wheels swiveled to the axle and draft rigging comprising a draw bar pivoted to the, frame, a compound two part steering lever pivot-ally supported on the axle loosely connected to the draft bar and connected with the steering wheels.

at. In a vehicle, the combination of a frame, an axle, a spring for supporting the frame upon the axle, draft rigging comprising a draw bar pivoted at its rear end to the frame, a steering lever comprising a front and a rear link hinged together, the rear link being pivotally supported on the axle, steering wheels swiveled to the axle and connected to the rear link and a loose connection between the draft bar' and front of the front link.

5. In a vehicle, the combination of a frame, an axle, steering wheels, a spring for supporting the frame upon the axle,-a draft and steering bar mounted on the frame, a two-part steering lever connected with the steering bar and having its two parts hinged together and having at its rear end a connection with the steering wheels. one of the parts of said steering lever being pivoted to the axle, and one or more'radius rods between the axle and the frame 6. In a vehicle, the combination of a frame, an axle, a spring suspension for the frame upon the axle, a two-part steering link comprising a front lever having a hub, a rear link having a yokoand vertical sleeve, the voke serving to pivot the rear end of the frontlink through the hub and allow av vertical hinging action and the vertical sleeve serving to allow pivoting of the rear link to the axle.

7. In a vehicle, the combination of a frame. an axle, a spring suspension for the frame upon the axle, and draft rigging in the form of a draw bar, means for locking the d aw bar to the fame or for allowing it to swivel with respect to the frame, a coupling head which can swivel with respect to the draw bar or be locked thereto, a compound steering lever which breaks vertically and has its rear linkportion pivoted to the axle, steering wheels swiveled to the axle and connected to the rear link portion and a loose connection between the front link and the draft rod and coupling head.

8. In a vehicle, the combination of 'an axle, a frame, a draft and steering bar pivoted at its rear to the frame and having a nub with a' pair or recesses, said vehicle 1 frame having a recess at the front, a coupling head pivoted to the draft bar and also having a recess and a latch provided with a portion which may be disposed in one pair of recesses to lock the draft bar to the frame and in the other set of recesses to lock the draft bar to the coupling head.

9. In a vehicle, the combination of an' axle, a frame, a. draft and steering bar, a coupling head pivoted thereto and a single swiveled latch device for optionally locking the draft bar to the vehicle. frame and allowing the coupling head to swivel with respect to the draft bar or on the other hand for locking the draft bar and coupling helid together and allowing the two to swivel with respect to the vehicle frame.

10. In a vehicle, the combination of an axle, swiveled wheels upon the ends thereof, a frame, a draw bar pivotally connected to the frame, springs mounted on the axle to 1 support the frame and allow vertical movements between the axle and the frame and draw bar, a steering lever pivotally mounted on the axle, a link connection between said lever and said wheels, and a self adjusting connection between the draw bar and the steering lever permitting vertical, movement of the draw bar relative to the steering lever but causing the lever to turn laterally with the draw bar.

In testimony whereof, I sign this specification.
